[Q] freezing and restarts when I use the swap - Android Q&A, Help & Troubleshooting

Hello,
I currently have a phone based on mt6577 where I started to modify the kernel to improve performance but I have a big concern about the swap. I want to enable zram.
I turn on when I swap it ends up freezing the system reboots instantly or with a random delay.
Kernel 3.0, 4.0.4 ICS
I tried to create a swap file system, the result is the same.
I have been looking for a while or could be the problem but without result.
A solution, an idea, a way?
Thank you.

How to uninstall the "minimized touchscreen bug" patch?

Hello, sorry for the lame question. I know, simple answer is "just re-flash it", but I would really appreciate another way advised to save the config and time.
I have lot of troubles after installing the subj. (http://forum.xda-developers.com/showthread.php?t=929941).
It's LG P500 running at 2.2 Froyo (stock, rooted, custom recovery):
- after applying the first version, battery management gone, access recovered by re-applying; but since then, scrolling became not so smooth as it was before; not a big problem, so I was waiting for next version;
- now, there is 1.1 version: applied that, but all the sounds individually matched to some contacts are gone, I can choose only standard sounds from /system/media, but not from /sdcard/media; tried to re-apply, get back to first version - no changes; get back to 1.1 - and now cannot choose those sounds in any system menu - for all the contacts, alerts etc etc.; but way more important, the I/O performance severely degraded, appearing as up to 10 second to open an app., which was never observed before; "SD tools" measuring shows degrading both R and W (~5 Mb/sec less now).
Is there standard stock 2.2 kernel available separetely, maybe switching back could solve these problems?
Thanks for any thought.
It's not a patch. It's a whole different zImage (kernel?). You may want to restore your backup. If you don't have one, I uploaded the stock 2.2 kernel. It's in the 2nd page of this subforum. Look for "unflash kernel".
I suggest u flash dev cavermans v3 kernel, I loved the response of it ever since I flashed it.
OK, thanks a lot for replies and links!
Yesterday, I re-installed a kernel, tried different versions... Unfortunately, something dramatically wrong with my phone.
With ringtones, it seems I ran into that problem:
http://forum.xda-developers.com/showthread.php?t=998520
- android does not aware of /whatever/media folder anymore.
With performance, it became a bit better after moving most of apps to SD card, but still unacceptable.
Probably, I have to re-flash the whole stuff

Help with some issues I don't understand

Hei guys, I'm new to this, barely managed to get adb working for the 1st time.
I kinda have 2 or 3 questions that I couldn't figure out entirely by my own.
1st - What's dalvik-cahce ? what does it do? what gets erased if I wipe it and what do I have to gain if I move it to the sd card?
2nd - How exactly does A2SD work? I'm currently using Link2SD and I don't know how it works and what exactly does that "linked" mean.... Or why should I use A2SD in the first place and not just use App2SD (which actually moves everything it's able to) from the market.
3rd Why does my phone crash? I tried noejins, mik's and andy's roms and they all crashed sooner or later, I got this black screen of death with some white writing on it for 1 second and the phone turned off. Is it because I'm overclocking to 122/787? That's the only common thing I could find - and - it didn't crash before I started overclocking. I think they call it "kernel panic" or something like that.
Thanks in advance.
1. Java bytecode compiler cache
2. No data lost, it is just cache. Will get recreated as needed or on reboot.
3. Link is a symbolic link pointing to another location. Google it.

some of the phones(lg-p500) cant be overclocked above 768 OC'ed >768 = Kernel Panic and uneven shutdowns like i face after overclocking above 768.
a2sd is different from app2sd....we cannot move dalvik cache and widgets to memory card using app2sd...using a2sd you can create a partition of the memory card where these things can be stored as if it is being stored in the phone memory....it saves you some space in the phone memory....
Kernel Panic is the UNIX equivalent of what you've been seeing all your life as a Windows user, the Blue Screen of Death.
When your operating system encounters an error it cannot recover from, it dumps all the information about it in a log file and reboots. The error is usually called 'fatal'.
See it this way, it's the computer version of jumping off a cliff, realizing that you're going to die and then having your sweetest memories flash in front of your eyes Only in this case the OS comes back to life.

My A101 Lags :(

Hi ! I'm having problems with my A101, i have the latest firmware and Urukdroid 1.6RC4, but since the beginning after I bought this, i have memory isses. it lags so bad. even playing Angry Birds is difficult for me.
what seems to be the problem ? please help
thanks
1. Do you use AnimatedWallpapers? Switch them off.
2. Use another Launcher as stock is rubbish
3. Did you switch the governor to interactiv?
4. How many apps did you install ?
look at overclocking a little to give it that extra boost!
if you have a fast sdcard also try using swap memory.
Another thing is your Urukdroid install on the internal memory or on a sdcard? if its the sdcard it can make it lag alot if its not fast!

[Q] Noob help - Rooted desire keeps freezing.!

Morning guys - i'm a sort of noob (go easy.!) that needs help with my HTC desire. I took plunge and decided to try rooting & applying custom ROM, but now have problems with the screen freezing completely at any point, then on restart the phone boots into the home launcher but screen does not respond or will not wake.
So far:
Rooted with unrevoked
HBOOT flashed to Cm7r2
Latest version of clockworkmod recovery via app
Aurora 4.1 (all dalvik caches wiped at correct points).
V6 supercharger applied on setting 5 (balanced).
Tried with kernel built in ROM (0.7) & gingercakes 0.9cfs no2way havs.
SD card partitioned with GParted (fat32 primary, 2gb primary ext4).
I've had the ROM working fine, the only other thing i can place it to is swapping the SD card, which i've changed from 4gb class to, to a samsung 16gb class 6. Does anyone think that this error could be anyway caused by the fact the card readers i've used (tried 2 different readers) both have had trouble recognising the 16gb card?? (Gparted still recognised it however)
Is it possible to be a hardware issue? Please note recovery works perfectly - wiping caches, reinstalling zip files, backups etc.....only problem is now this freezing of home launcher and no response.
Any help be greatly appreciated, give me a nudge if i haven't given enough detail.
Regards, Nick.!
Additional:- Tried unsupercharging & rebooting - no difference.
Only other thing i can think that i've done prior to the fault is attempting to install busybox for V6 supercharger - which failed every time and affected my root access on the phone. I've found that the Aurora ROM has busybox installed already. However, is it possible me trying that install has somehow affected the rooting of the phone?
So many questions, sorry guys!
Bump.....would ADAO file manager (which isn't on google market I notice) affect anything on ext4 perhaps? That was one app that i downloaded from net.
Have you tried reverting your busybox to the default version? Also, are you overclocking and or overclocking? Going to high or to low with CPU speed can cause problems like that. It has also been said that partitioning an SD card can damage them, which may be an issue you have now. You could try formatting the SD card to its default state and run like that for a while. I ran a 16gb SD card in a Droid Eris for months and it never caused a problem like that. Of course, I didn't have a partition set up on it.

I've literally left the settings for speed in daemon controller alone, although i'm still learning and not sure if they are default overclocked or not?
Possibility with the SD card, i'll give it a try for sure, that'd mean i'd have to revert to an alternate ROM would it, as Aurora specifies an ext4 partition?
Thanks again though, it's a start at least
Do you set profiles in SET CPU?

Excuse noobie brain here, where will i find those CPU settings?
If so, fully wipe and install again. And what rom are you using currently that causes freeze?
Accidentally sent from my Google Nexus S using XDA Premium
Aurora V4.1 ROM i'm using. Don't think it's the ROM itself as i have had it stable for week or so, before swapping SD card from 4gb to 16gb.
I'm thinking this may be the root cause as i've just tried a complete fresh partition with Gparted & fresh install of literally just the ROM itself and on first boot it froze again. Rebooted and now seems to be stable with nothing reloaded back on it but we'll wait and see. If it freezes again i'll try my 4gb card. Didn't want to revert back to that as its only class 2.
[Q] Noob help - Rooted desire keeps freezing.! Update...!
UPDATED - Still getting same problems - have now tried a different SD card & alternative ROM (Cool3d v5).
Is it possible it could be heat related fault? The more i use the phone the more readily it happens - from the occasional freeze (okay after reboot) to complete freeze and no response on every reboot.
Does the CPU therefore have a cut out or could be freezing based on the settings that are initially loaded through daemon controller? What are safe settings for the min/max values?
Only other thing i've noticed is once fault starts to occur - clearing dalvik cache in recovery is quite unresponsive - menu holds before allowing me to clear.
Got to get to the bottom of this - don't want to revert back to original, or throw my phone in the river!!
Save clock is 1ghz. No over clock is the safest.
Do your phone wear case? If yes, it may be the caused of heat.
I'm sure the rom caused you the freeze. You can try to change a more stabler rom, eg aosp

Bit more progress - as my phone literally would freeze on loading home launcher, i connected it to pc and mounted via recovery - and deleted everything i could see for V6 SUPERCHARGER - and hey presto, very slowly, but phone booted up and is now working again.
I see the devs of V6 say about removing hardtokill if any lags occur - i think it's this portion of the script affecting my bravo.
SO, i'm going to run it totally without V6, and may try to just run the memory portion, but the instructions to disable hardtokill are a little unclear to me, could you guys tell me in simple terms how to acheive??
Thanks again for all your responses, a great help
V6 now off and all fresh re-installed with cpu max turned down also, and set to ondemand gov, will see how we go
[Q] Noob help - Rooted desire keeps freezing.! PT3.!
Still no joy with this issue guys - pulling my hair out now - after a few hours use (usually overnight) phone just freezes, then freezes on reboot, before getting worse and now will not pass alpharev's boot screen.
Installing fresh gets me into home launcher, but becomes unresponsive and freezes again.
I've tried different ROM's, different SD's, basic clean install, all without any luck. I'm thinking now it is more a hardware issue with the phone?

Did you wipe data/cache partitions/dalvik cache before flashing the rom? Did you wipe dalvik cache and cache partitions after flashing the rom?
Yep all wiped before and after.

Have you tried flashing a new kernel?
Yep fault happens with any kernel I've tried (so far 0.9c no2way havs cfs, also 2way version, 0.8f cfs havs, 0.7c)

Has your device went through any physical damage (around the time the problem started)?
No physical damage apart from the battery cover being pulled off more than once(!) and a lot of obscenities being flung it's way, lol! But no, not dropped or damaged at all.
I've used the phone now all afternoon, longer than normally, with the same details on same hboot, but left some of the sense widgets off the home launcher, and it hasn't locked up once.

Does it use 256 mb of ram when you're doing stuff or just right after boot for no reason? Try either overclocking it or use Auto Memory Manager https://play.google.com/store/apps/details?id=com.lim.android.automemman&hl=en. If you need help try asking some of the devs directly I suppose.
well when i go online it slows down alot, the button light turn on and off a bunch, im using Advanced Task Killer & Quick System Info Pro
